'7 Claims.

This invention relates to an improved shipping container made of fibre board or similar material.

It is one of the objects of the present invention to provide a strong and durable container constructed from a single piece of fibre board with a minimum of waste.

It is another object of this invention to provide a novel container which may be formed about the article to be enclosed, thereby efiecting considerable saving of labor and storage space, and which, upon being formed, is made ready for shipment by the application of a single strip of gummed tape. V

Another object of the invention is to provide a container in which the end flaps are so constructed that they will, without the aid of stitching, stapling or slots, hold the formed container firmly and securely without bulging and in a manner to prevent crushing.

Another object of the invention is to provide a container of the class described which will be inexpensive to manufacture and simple to construct.

Other objects of the invention will be apparent from the description and claims which follow.

In the drawings like reference characters denote similar parts throughout the several views.

Figure 1 is a plan view of the blank from which the container comprising the present invention is formed.

Figure 2 is a perspective view of the formed container.

Figure 3 is a perspective view of the container, partly opened.

The blank from which the container comprising the present invention is formed, is cut and creased as shown in Figure l. Creases I and 2 divide the blank into bottom 3 and sides 4 and 5. Bottom 3 is provided with end flaps 6 and I separated from the bottom 3 by creases 8 and 9, respectively. Flaps 6 and 1 are tapered on either side at ID to form decreased outer edges II and I2, respectively.

Side 4 is separated from cover portion l3 by crease l4 and is provided with end flaps l5 and I6 separated from side 4 by creases l1 and I8, respectively. Cover portion I3 is provided with end flaps l9 and 20 separated from cover portion 13 by creases 2| and 22, respectively.

Side 5 is separated from cover portion 23 by crease 24 and is provided with end flaps 25 and 26 separated from side 5 by creases 2! and 28, respectively. Cover portion 23 is provided with end flaps 29 and 30 separated from cover portion 23 by creases 3| and 32, respectively.

The container, when setup as shown in Figure 2, is in length equal to crease I, in width equal to crease 8, and in height equal to crease I'I. Flaps l9 and 20, and 29 and 30, extend from the cover portions l3 and 23, respectively, a distance equal to the height of the finished container.- Similarly, flaps 6 and I extend from bottom 3 a distance substantially equal to the height of the finished container. Flaps l5 and I6, and 25 and 26, may extend from sides 4 and 5, respectively, any suitable distance, preferably not to exceed one-half the width of the container, as in setting up the container, the best results are obtained if the flaps l5 and 25, and I6 and 26, do not overlap. The cover portions 13 and 23 extend from sides 4 and 5, respectively, a distance preferably equal to one-half the width of the container, so that the outer edges of said cover portions will be adjacently disposed but not overlapping.

The blank exemplified in Figure 1 may be cut to form containers of varying sizes, but from the above it will be seen that the blank, regardless of the dimensions of the desired container, may be cut from a piece of material which in its shortest dimension is equal to once the length plus twice the height of the container, and in its longest dimension equal to twice the width plus twice the height of the container to be formed.

In practice, a supply of blanks shown in Figure 1 may be stacked upon a table or bench in front of an operator. The article to be enclosed is placed upon bottom 3, and the container formed thereabout and sealed ready for shipment by the operator, who proceeds by first folding one end and then the opposite end. The container is formed by bending sides 4 and 5 vertically at right-angles to bottom 3, the flaps l5 and 25 inwardly to crease 8, the cover portions 13 and 23 over to rest on flaps l5 and 25, respectively, the flaps I9 and 29 downwardly against flaps l5 and 25, respectively, and flap 6 upwardly againstflaps l9 and 29. The operator, while holding the completed end against a ledge provided on the work table or in any other suitable manner, then proceeds with the opposite end by bending flaps l6 and 26 inwardly to crease 9, the flaps 20 and 30 downwardly against flaps l6 and 26, respectively, and flap l upwardly against flaps 26 and 30. As shown in Figure 2, the outer edges of cover portions I3 and 23 will meet at 33 and form a central slit in the cover of thecontainer extending from end to end. The container is then sealed by placing a strip 34 of gummed tape over the cover portions 13 and 23 at slit 33, and extending the same down upon end flaps 6 and I. The container is thus firmly sealed and does not require any additional fastening means.

It will be seen that flaps l9 and 29, and 2!) and 30, are free at their outer and side edges to facilitate folding and unfolding of the cover portions and in the formation of the container, will rest upon bottom 3 to thereby act as supports between the cover and bottom to prevent crushing. It will also be seen that the several end flaps extending from each of the panels, upon being bent at right-angles thereto, will act as transverse supports to prevent bulging.

The container comprising the present invention is easily formed and sealed ready for shipment in one continuous operation. As shown in Figure 2, the finished container is devoid of protruding ends which may be caught or snagged during handling.

As shown in Figure 3, the container may be easily opened for removal of the contents by piercing the gummed tape with the thumb nail ora sharp instrument along slit 33 and giving a slight pull oneither of the top portions l3 or 23.

The term fibre board as used in the claims will be understood to include straw board, paper, pulp board and similar foldable materials adapted for the manufacture of containers.
